Narrative:
Mosquito NS875: Took off at 22:47 hrs for Night Intruder mission to Lake Constance and Strasbourg. 06/04/1944
Crashed 4 km off Uttwil into Lake Constance on Swiss side of lake at 00:15 hrs.07/04/1944
Since the two crew members died in the crash, the reason for the crash is still unclear. The only thing that is certain to this day is that the sky that evening was cloudless and the visibility was very good thanks to the full moon. The Swiss Army observation post stationed near Romanshorn was able to detect several planes that night, but without identifying them. The last sighted aircraft flew over Altnau at an altitude of about 3000 meters a few minutes after midnight. Seven minutes later, the aircraft in question left Swiss airspace heading south-east at Arbon. A few minutes later, a firefight from the direction of Friedrichshafen was taken by the observer. The 26th Flak Division with its 88mm anti-aircraft guns was stationed at the airfield near Friedrichshafen. After the battle, the engine noise of an airplane became louder again before it suddenly fell completely silent. Apart from a wing, a strut with impeller and three fuel tanks, which floated on the water surface, no other parts could be recovered. The machine is located about 200 meters deep in Lake Constance.

S/Ldr (33574) Michael NEGUS DFC (pilot) RAF - killed
